Find the Domain x^2-3x-28=0

Problem

x2−3*x−28=0

Solution

1. Identify the type of expression. The expression x2−3*x−28 is a polynomial.

2. Determine the domain constraints. Polynomials are defined for all real numbers because there are no denominators containing variables, no square roots of negative numbers, and no logarithms.

3. State the domain. Since there are no restrictions on the input x the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
